    Dr. Bracero reviewed regional blocks and presented the Kang et al article. Superior trunk block was compared with interscalene brachial plexus block for 80 patients undergoing arthroscopic shoulder surgery. They found no significant differences in pain score 24 hours after surgery. However, the superior trunk block resulted in significantly less hemidiagphragmatic paresis (76.3% vs 97.5%).

    Dr. Alam gave a concise presentation about the Makkar et al article. This randomized control trial compared 2032 patients assigned to either transcatheter or surgical aortic-valve replacement in terms of death or stroked within 5 years. Moreover, they compared transfemoral vs transthoracic access. They found no significant differences between the TAVR and surgical approaches. However, incidence of death or disabling stroke was higher after TAVR than after surgery in the transthoracic-access cohort. In the discussion, it was noted that TAVR has changed how we treat cardiac care patients. Now the majority of our cases are TAVR.

    The final article of the evening (Joffe et al) was about failed intubation and is an important one for our specialty. It was presented by Dr. Kang. This closed claim analysis compared 102 claims during 2000 to 2012 with 93 claims during 1993 to 1999. Although there was a higher proportion of death in the more recent claims, the more recent patients were sicker and had more emergency procedures. There was also an increase in the number of claims for non-operative settings. We discussed the importance of good judgement, having a secondary plan and asking for help during a difficult tracheal intubation.

    Dr Mathew gave a terrific review of the Schwenk et al report of a randomized controlled trial of patients undergoing primary total hip arthroplasty. The authors found that patients given mepivacaine ambulated sooner (p < 0.001) and were more likely to be discharged the same day (p < 0.014) in comparison to patients given hyperbaric or isobaric bupivacaine. There was some discussion regarding how the n number was obtained.

    Dr. Figueroa gave a concise review of the article by Jang et al. It was really interesting to hear about the potential use of nitroglycerin in pediatric patients. The study concluded that subcutaneous nitroglycerin injection before radial artery cannulation improved the first attempt success rate (91.2% vs. 66.1%, p<0.002). There was also a decrease in the complication rates in patients given ntg.

    Dr. B Kim gave a thorough review of the Khanna et al observational trial on opioid-induced respiratory depression. The study concluded that the PRODIGY Score could enable prediction of respiratory depression in patients receiving opioids on the general care floor. Dr Bergese noted that the PRODIGY study has found that these events occur primarily either in the late afternoon or late in the evening. This will be published in a forthcoming study.

    Dr. Shuaib gave a terrific review of the article by Karaaslan et al. It was really interesting to hear about all the findings that LMA-S provided more effective airway protection than ETT in preventing blood leakage in septoplasty procedures. A comparison of LMA vs ETT was discussed . There was consensus that LMA positive pressure ventilation is avoided and that spontaneous ventilation with an LMA is safest.

    Dr. Watson gave a fabulous review of the article by Y. Li et al. The authors considered cognitive disorders at postoperative day 5-7 with patients undergoing propofol anesthesia vs a SevoFlurane based anesthetic. They found no differences between the groups. However, high levels of blood interleukin-6 after surgical incision may be an independent risk factor for delayed cognitive recovery.

    Dr. Kant gave a terrific review on the Murphy et al paper. It was really interesting to hear about intraoperative methadone use for reduction of postoperative opioid requirements. Because patients showed improved pain scores and improved satisfaction it will be interesting to see if there will be increased use of this. During the discussion it was noted that methadone is not used frequently but that it actually works very well.

    Dr. Xiao summarized the article by Carella et al well. This article evaluated the influence of regional scalp block on hemodynamic stability during the noxious stimulus of skull pin fixation, skin incision, bone incision and dura Mater incision as well as its influence on intraoperative anesthetic agent consumption. The authors found that the block did provide adequate and prolonged postoperative pain control as compared to placebo. It was discussed that it’s always good to see differing ways of care. As to its use at SB -that is something for future discussion with the neurosurgeons.
